This claw is used to work the soil to a depth of +/- 15 cm. It is used before sowing or planting to break up the topsoil, after airing the soil at a deep level with the GUERILU spading fork for example.
You can also work in depth between the rows and bring creeping weed roots (quackgrass) to the surface without cutting them and therefore without multiplying them. Its working width is about 25 cm.
You can attach two, one beside the other to double the working width.
